we get what we see. that's an issue coming up. these people are networking. they spread the word. sidewalks are cool game, trees are cool, they don't touch that. you're exactly right. i experience in my own life. we're going to have to open people, we're going to have to focus on sidewalks unfortunately. >> if i can just add, we're a network, too. this is a network. your city is a network. the city is networking with the police, with the business units, with the volunteers, with the seniors groups, with youth groups, whoever is walking those streets, cleaning those streets, going down there to enforce by law and properties, they all need to be paying attention to these things and it can be as quick as a saying. recently we've noticed x is happening. we're asking you to report it to this department, this person so we can proactively deal with it. it's the same thing if you guys are getting internet viruses or some kind of criminal behavior happening through your network. they inform you of it. and it's the same thing.
